I'm developing a full sized electric based on the 2 stroke YZ platform. Water cooled DHX Hawk 40 motor (40-50hp), 72v Sony based water-cooled battery pack 3.9kw/hr, water-cooled Sevcon Gen 4 controller, ANT BMS. Projected weight is approximately 240 lbs. My prototype is about 70% complete at this time. If folks are willing to pay 11K for a bike with no manufacture parts or service support I'll bet they'd be willing to do the same for a bike with better performance and readily available parts and support. Of course, the "better" performance is yet to be proved . . . . . YET!
Note: More build details for my full sized and other conversions can be seen at my Instagram #maxvonauto.
My KTM 65 and 85 Conversions are doing well at the local SoCal MX tracks.
